The origin of homochirality in terrestrial biological molecules (dominant L-amino acids and D-sugars) remains an unresolved important problem in the study for the origins of life. One of the most attractive hypotheses for the origin of homochirality is nominated as “Cosmic Scenario”; polarized excitation sources in space triggered asymmetric reactions of complex organic molecules including amin...

The ability to dynamically control chirality remains a grand challenge in chemistry. Although many molecules possess chiral isomers, lacking their isolation, for instance during photoisomerization, results racemic mixtures with suppressed enantiospecific properties. Here, we present nanoporous solid which and enantioselective enrichment is induced by circularly polarized light (CPL). material b...

Die 3D-Helixstruktur eines nicht-symmetrischen Poly(diphenylacetylens) (PDPA) mit dynamischer zirkular polarisierter Lumineszenz (CPL) wird im Forschungsartikel von Félix Freire et al. vorgestellt (e202115070). Durch Konformationsänderungen in der Substituentengruppe kann eine Helixinversion des PDPA ausgelöst werden, wodurch ein CPL-Schalter entsteht Massenspektrometrie Heterocyclenchemie Flüs...

The precise co-conformation regulation of topologically chiral [2]catenanes under two different external stimuli led to the construction a bidirectional circularly polarized luminescence (CPL) switch, as reported by Xiao He, Wei Wang and Hai-Bo Yang et al. in their Research Article (DOI: 10.1002/anie.202210542). results provide not only an attractive approach toward multistate CPL switches for ...

The combined effects of growth pattern (GP) and dietary CP level during rearing (2 to 22 wk of age) on body composition and performance were investigated in broiler breeder females from 0 to 40 wk of age. One-day-old pullets (n = 768) were randomly allotted to 48 pens according to 2 growth patterns (standard = SGP and high = HGP) and fed using 1 of 3 dietary CP levels (high = CPh, medium = CPm,...

Brugia malayi, a parasitic nematode that causes lymphatic filariasis, harbors endosymbiotic intracellular bacteria, Wolbachia, that are required for the development and reproduction of the worm. The essential nature of this endosymbiosis led to the development of anti-Wolbachia chemotherapeutic approaches for the treatment of human filarial infections. Our study is aimed at identifying specific...

design and synthesis of high-performance hydrogenstorage materials. Although the weakest X-ray scattering amplitude of hydrogen made it difficult to determine their structure, we have succeeded in the first direct observation of elusive H2 molecules adsorbed in the nano-channels of a metal-organic porous material by the in situ synchrotron powder diffraction experiment of gas adsorption and by ...
